Supersymmetric and Gauge-Invariant Path Integral Measure in $\mathcal{N}=2$ SQCD

We define $\mathcal{N}=2$ supersymmetric and gauge-invariant path integral measure in $D=4$, $\mathcal{N}=2$ SQCD in terms of $\mathcal{N}=1$ superfields. As a further consequence, we derive the $\mathcal{N}=2$ version of the chiral anomaly in an $\mathcal{N}=2$ supersymmetry-preserving manner.
